The "Therapeutic Window" refers to the range of drug dosages that provides effective treatment without causing harmful side effects. It is crucial for ensuring that a medication achieves its desired effect while minimizing the risk of toxicity. The therapeutic window is determined by measuring the drug's effectiveness and safety levels in the body. Understanding the therapeutic window helps healthcare providers prescribe the right dosage of medications, such as antibiotics or pain relievers. If the dosage is too low, the drug may not work effectively; if it is too high, it can lead to adverse effects. This balance is essential for optimal patient care.
